Question 260312
There are two options here.
option 1 - base angles = 3x and non base angle = x+50.
all angles add to 180, so we get
{{{3x + 3x + x+50 = 180}}}
{{{7x + 50 = 180}}}
{{{7x = 130}}}
{{{x = 18.57}}}
which means two angles are: 55.714 and the last angle is: 68.57

option 2 - base angles = x+50 and non base angle = 3x.
all angles add to 180, so we get
{{{3x + x+50 + x+50 = 180}}}
{{{5x + 100 = 180}}}
{{{5x = 80}}}
{{{x = 16}}}
which means two angles are: 66 and the last angle is: 48
